PAPER-JACKETED CAN. j

Specification of Letters Patent. Patented July 20, 1915.

Application leii August 15, 1913. Serial No. 784,883.

lie it known that I, BEN K. Fono, a citizen of the llnited States, residing in letroihin the county of lVayne and State of Michigan, have invented a new and useful lmprovenient in Paper-Jaeketed Cans, of' which the following is a specification. y

This invention relates to an improvement in the construction ot' paper jacketed sheetnietal cans and it consists in the novel parts and devices and coi'nbination of parts and devices hereinafter set forth and made the subject', matter ot' claims.

.ln the accoinj'ianying drawing, which forms a part olf' this specification, Figure is a top or plan view of a jacketed can containing the invention; Fig. 2 is a vertiial section ol.' the saule. on the line 2-2 of liig. l Figi'. l a brolien section similar to that of Fig. 2 hut upon a somewhat larger scale; Fig'. l a cross section of the jacket.

lleretoore paper jackcted cans have been made with the paper applied to the sheetnietal can body by winding the paper coat-ed with an adhesive directly upon the can body itself vso that the protecting shell ot.' paper adheres to the sheet-nieta] body and in a sense luiconies one with it. This construction, .vhile it possesses sonic advantages is attended with certain disadvantages which the present invention is particularly designed to evercon'ie. ln the present structure the paperl shell or jacket; is inade by winding the saine upon u cylinder or form and is thereal'ter applied and secured to the can by means to he described more fully, with the result that an air space operating as a nonconductor is l'orined around the can; and al; the salne'tinxe with the i'urther result that any dents or injuries in the shell are not trmisinited to the sheet-metal of the canv body itsell; and the lui-ther result that when necessary to repair leaks the sheet-metal vessel may be removed l'roin the shell or in case olt injury to the shell it may be removed. l'roin the vessel and n new shell supplied; and the further result that the manufacture ol' the jacketed can as a uhole is unich simplilied and cheapened; while at the saine time a vastly superior and much cheaper jacket to the wood veneer jackets 'in Com.- inon use is produced.

ln the said drawing),v is shown the sheet. metal vessel or can to be jacketed consisting;r o'l' the cylindrical sides A, the bottom end i5 and the top end C joined to the sides by the seams l), D. In the instance illustrated the.

top end 1 is of the ordinary lla-t form which is the. preferred form but some of the advantages of the invention may be attained by use of the ordinary conical can breast it' that forni of can shallA be the one to be jacketed, as is obvious. The paper shell composed of a strip of adhesively coated paper Wound upon itself on a mandrel into cylindrical forni with the adhesive on the outside surface is represented at E. Ey is a circular wooden disk forn'xing' the bottom of the j acket, and E is a similar disk forming the top of the jacken-in case of a breast can the top disk is of course omitted. These disks are to be applied after the can is inserted in the jacket and are held in place and the jacket held upon the can by the Z- shaped metal holding strips F, F', the outer flanges of which are curved into the yie1ding pa per as at f, 7", making a irm connection which holds the can from up and down movement. litw n the surface of the can and the jacket t t.. ,i sides is the air space Gr,

. and at the top and bottoni the air space G',

G so that in the preferred form the entire can is surrounded ,y a non-conductingspace. lhe seams l), l) se Je to space the jacket from the can both at sides and top and bottoni. f

Ylt is above mentioned that the stripA of paper formingl the sides of the jacket is coated with adhesive on its outside surface. ly this is meant the surface farthest from the can.y The purpose is that the inside of the jacket may be letty entire-ly free from the adhesive when the strip adhering to itseltu is rolled into the cylindric form and so that the outside of theforlned jacket Will be coated. with the glue if that adhesive be used and which outside coating of glue may be rendered insoluble as for example by spraying' the saine with formaldehyde or With a. chromium salt. The top end C is cut at one side with a cavity to accommodate a pouring; spout il and is cent-rally slotted as at l to permit the protrusion of the handle K. j

l claim:

1. A paper jacketed can comprising in combination, a can made of sheet metal and having its top land bottom seame'l to the sides and au inclosing jacket the Walls of which are made of a sheet of paper coiled 'inpon itself independently of-thecan and ar-' ranged outside of the can top and .bottom and the seams thereof, top and bottoni disks arranged within the jacket, and sheet metal` holder strips lit-ving flanges whichengage the outer faces of the said disks and having their edges crimped `into the outer Walls of the paper jacket at the ends of the latter, substantially as specified.

2. A papei'- jacketed can comprising, in

icombination; a can made of sheet metal and having its top and bottom seamed to the tigdres, the said seams extending horizontally ond the side Wallsand vertically beyond y V,th'elieads of the can; 'a jacket'the Walls of. v

holder strips arranged at the outer sides of the said disks 'and curled over and crimped into the paper of the jacket at the ends thereof.; substantially as speced. l
